UNITED THOMAS B. .AULT, F KNOXVILLE, TENNESSEE.

To all whom Be it kno PLOW FOR BREAKING AND PULVERIZING THE SOIL.

Application filed February 9, 1922.

7/ it may concern:

wn that I, THOMAS B. AULT, a

citizen of the United States, and a resident of the city of Knoxville, in the county of Knox and the State of Tennessee, have invented a certain new and useful Improvement in Plows for the Soil; and I Breaking and Pulverizing do hereby declare the following to be a full, clear, and exact descrip- 1 tion of the invention, such as Wlll enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings,

and to the tion.

of reference marked part of this specificacharacters My invention relates to means for breakmg and pulverlzing the SOll, the primary object of WI iich is the provision of a simple device for breaking and pulverizing the soil by means of a lighter plows, my its circular its sharp on cut its way device being draft plow than other so constructed with bottom and U-shaped share and tting edge in front, that it will through the soil on both sides,

the pressure being no greater on one side than it 1s on the other, and the device being so construct it w1ll cut 1 ed with its U-shaped share that ts way through the soil on both a different place as other plows do. hen

the U-shaped plow is drawn through the soil, the so passing through the falls back i Further,

i1 is slightly raised and after U-shaped plow the soil :0 its original bed.

my invention, having the circular bottom and the U-shaped share with its cutting edge in front and extending up on each side, will allow it to pass through the soil with much less friction than other plows.

Further, other plows the draft be ing; second,

my invention is for the ing it preferable to following reasons: First, lighter enables deeper plowpulverizes the soil better than other plows; third, it works on a hillside as well as on level ground; fourth, it does not leave any furrow to contend with; and

fifth, it leav clods.

es the soil smooth and free from Serial No. 535,409.

My invention is fully described in the following specification and while, in a broader aspect, it is capable of embodiment in numerous other forms, a preferred form thereof is illustrated in the accompanying drawings.

Fig. 1 is a view in side elevation of a device embodying my invention;

Fig. 2 is a view lookng directly at the front,

Fig. 3is a perspective view of the upright standard;

Fig. 4 is a perspective view of the device shown in side elevation in Fig. 1,

Fig. 5 is a perspective view looking from beneath;

Fig. 6 is a perspective view of a U-shaped circular bottom share;

Fig. 7 is a perspective view showing the point and runner.

In the figures the numeral 1 indicates a plow beam; 2 indicates an upright standard; 3 indicates a U-shaped share with a circular bottom and sharp cutting edges (indicated by B, B) in front and extending up on each side; 4 indicates the point and runner which extends from the front to the rear of the invention; and A is a curved wing in Figs. 4 and 5 and showing the wing extending out on one side from the point and runner. The part 3, which comprises my invention, is securely riveted to 4, the plow beam is securely bolted to standard 2, and parts 3 and 4 are securely bolted to the standard 2, making the point and share easy to attach and detach.

I am aware that prior to my invention there have been plows made with similar beams, points and upright standards, there fore I do not claim such a combination broadly, but what I do claim as new and for which I desire to secure Letters Patent, 1s:

1. In a plow structure for breaking and pulverizing the soil, consisting of a runner and share, in combination with a beam and standard, the share extending outwardly and upwardly on one side from the runner, and extending outwardly and upwardly on the other side of the runner, and in line with the standard, the share being securely riveted to the runner, substantially as described.

2. In a plow structure for breaking and In testimony whereof I have hereunto set pulverlzing the soil, eonsistlng of a runner my hand 1n the presence of two subscribing and share, the share extending out on either Witnesses.
